bug#587: 23.0.60; To source or not to source (from help)

[Lennart Borgman (gmail)]

If you do C-h v and look at a variable and click on the library link in 
the help buffer you will go to the file in your current Emacs tree. If 
you do C-h f to look at a function and do the same you will be taken to 
the cvs checkout file instead.

I suspect you compiled Emacs in the checkout directory and then copied
the Emacs tree to another directory.  In this case the following might
happen: As for C-h f `describe-function-1' will execute

       ;; See if lisp files are present where they where installed from.
       (if (not (eq file-name 'C-source))
	  (setq file-name (find-source-lisp-file file-name)))

which sets `file-name' to the ".el" file from the checkout directory
(because you did compile it there) and installs the corresponding
reference in the hyperlink.

As for C-h v `describe-variable' does _not_ care whether you compiled in
another directory and simply goes to the file supplied by `symbol-file'.
You could try inserting the snipped above in `describe-variable'
immediately before the line

	      (if file-name

and see whether it now jumps to the checkout directory instead.


Personally, I'd prefer something like the following in both cases:

       (unless (or (eq file-name 'C-source)
		  (file-exists-p file-name))
	(setq file-name (find-source-lisp-file file-name)))

I use the normal

   make install INSTALL_DIR=...

Yes, I guess that is correct.

Thanks martin. I think a variable (or an option) for which elisp to go 
to would be the best. Is there any reason not to have that?

I never use that.  Are the ".el" files copied as well in that case?

Did you verify it?

We'd have to do something similar for definitions in the C-sources too.
Do I suppose correctly that the C-sources are not copied automatically
when you explicitly specify the install directory?  I'm too lazy to look
into this ...

I did not look at the details again since I did not have time to fix 
this. I notice that C-h v takes me to the Emacs install tree I am using 
and C-h f takes me to the CVS checkout tree where I compiled Emacs.

I have seen no problems with the C sources. I always get to the CVS 
checkout tree from C-h v,f.

I did not even know they could be copied when you do make install. How 
do you do that?

I'd use file-readable-p, but otherwise, it sounds fine,

We can consistently try to go to the compile directory or to the install
directory first, whatever people want.  A problem with the former
approach is that the definition might not be there any more, e.g., after
a fresh checkout.  That's why I would probably prefer the latter.

I would suggest something like this:

- A variable to decide where to go
- Possibly there should be a separate variable for the src tree
- If not possible to go there:
   * If no other choice then give an error
   * Otherwise ask user wether to go to the other place
     (checkout/install)

An option, I suppose.

Rather not.

I think asking the user is some kind of overkill, we should make this
part of the option - always go to build dir, always go to install dir,
prefer build dir, prefer install dir.  In any case we have to make sure
first that implementing such an option won't violate the feature freeze.

Sounds good.

Currently there is a bug to fix and I believe implementing this might be 
the best way to fix the bug.

Let's not introduce any new variables at this point.  We can revisit
this issue after the release, but I'm not convinced that it's useful to
enough people to add variables for controlling this behavior.  People
who care enough about this can write their own advice.

Martin, could you change the trunk to do what you suggested
(i.e. checking the install directory first)?  Thanks.
